These Standards are applicable to databasing laboratories performing DNA analyses on DNA samples obtained from identified subject(s) for purposes of entering the resulting DNA profile or DNA record into a DNA database. If, in addition, the databasing laboratory is performing DNA analyses on known or casework reference samples considered evidence by that laboratory, the databasing laboratory shall:
- Follow the Quality Assurance Standards for Forensic DNA Testing Laboratories for the known or casework reference samples; or
- Follow these Standards including the additional requirements for known and casework reference samples in 184.108.40.206.1 and 220.127.116.11.
This document consists of definitions and standards. The Standards are quality assurance measures that place specific requirements on the laboratory. Equivalent measures not outlined in this document may also meet the Standard if determined sufficient through an accreditation process.
These standards shall take effect July 1, 2009.

These Standards describe the quality assurance requirements that laboratories performing DNA testing on database, known, or casework reference samples for inclusion in the Combined DNA Index System (CODIS) shall follow to ensure the quality and integrity of the data generated by the laboratory. These Standards also apply to vendor laboratories that perform DNA testing on database, known, or casework reference samples in accordance with Standard 17. These Standards do not preclude the participation of a laboratory, by itself or in collaboration with others, in research and development on procedures that have not yet been validated.
As used in these Standards, the following terms shall have the meanings specified:
Accredited laboratory is a DNA laboratory that has received formal recognition that it meets or exceeds a list of standards, including the FBI Director’s Quality Assurance Standards, to perform specific tests, by a nonprofit professional association of persons actively involved in forensic science that is nationally recognized within the forensic science community in accordance with the provisions of the Federal DNA Identification Act (42 U.S.C. §14132) or subsequent laws.
Accuracy is the degree of conformity of a measured quantity to its actual (true) value.
Administrative review is an evaluation of the report and/or supporting documentation for consistency with laboratory policies and for editorial correctness.
Analyst (or equivalent role, position, or title as designated by the Laboratory Director) is an employee that has successfully completed the laboratory’s training requirements for database, known, or casework reference sample analysis; passed a competency test; and has entered into a proficiency testing program according to these Standards. This individual conducts and/or directs the analysis of database, known, or casework reference samples and interprets the resulting data from these samples.
Analytical documentation is the documentation of procedures, standards, controls, and instruments used; observations made; results of tests performed; and charts, graphs, photos, and other documentation generated which are used to support the analyst’s conclusions.
Analytical procedure is an orderly, step-by-step process designed to ensure operational uniformity and to minimize analytical drift.

Casework reference sample is biological material obtained from a known individual and collected for purposes of comparison to forensic samples.
CODIS is the Combined DNA Index System administered by the FBI. CODIS links DNA evidence obtained from crime scenes, thereby identifying serial criminals. CODIS also compares crime scene evidence to DNA profiles obtained from offenders, thereby providing investigators with the identity of the putative perpetrator. In addition, CODIS contains profiles from missing persons, unidentified human remains, and relatives of missing persons. There are three levels of CODIS: the Local DNA Index System (LDIS), used by individual laboratories; the State DNA Index System (SDIS), used at the state level to serve as a state’s DNA database containing DNA profiles from LDIS labs; and the National DNA Index System (NDIS), managed by the FBI as the nation’s DNA database containing all DNA profiles uploaded by participating states.
CODIS administrator (or equivalent role, position, or title as designated by the Laboratory Director) is an employee of the laboratory responsible for administration and security of the laboratory’s CODIS at a laboratory that owns the database and/or known samples.
Competency test(s) is a written, oral, and/or practical test or series of tests designed to establish that an individual has demonstrated achievement of technical skills and met minimum standards of knowledge necessary to perform database DNA analysis.
Competency is the demonstration of technical skills and knowledge necessary to perform database DNA analysis successfully.

DNA type (also known as a DNA profile) is the genetic constitution of an individual at defined locations (also known as loci) in the DNA. A DNA type derived from nuclear DNA typically consists of one or two alleles at several loci (e.g., short tandem repeat loci). The DNA type derived from mitochondrial DNA is described in relation to the revised Cambridge Reference Sequence (Nature Genetics  23:147).
